Abstract
The invention discloses synthetic leather slurry with high wear-resisting property and a preparation method of the synthetic leather slurry. The synthetic leather slurry consists of the following raw materials in parts by weight: 60-70 parts of thermoplastic polyurethane, 10-15 parts of diisocyanate, 2-4 parts of fatty alcohol-polyoxyethylene ether, 6-8 parts of aluminum silicon micro powder, 20-35 parts of aluminum oxide, 0.5-1.2 parts of propylene epoxide phenyl ether, 2-4 parts of triethylamine, 0.4-0.6 part of sodium sulfate, 3-4 parts of maleic anhydride, 5-6 parts of molybdenum disulfide, 5-7 parts of polyvinyl pyrrolidone, 8-10 parts of groundnut leaves and 30-35 parts of N-methyl pyrrolidone. The synthetic leather slurry with high wear-resisting property disclosed by the invention takes aluminum oxide as filler, has relatively good wear resistance, flame resistance and relatively high humidity resistance in comparison with the conventional slurry, is unlikely to deform under affection with damp and at a high temperature; meanwhile, the added molybdenum disulfide and the modified groundnut leaves can be used for improving the wear-resisting property and the heat resistance of the slurry while improving the material strength; and the aluminum silicon micro powder is added, so that the mobility of the slurry is greatly improved. And the synthetic leather slurry is low in preparation cost and environmentally friendly.
Description
Technical field
The present invention relates to a kind of slurry used for artificial leather, be specifically related to a kind of synthetic leather slurry with high-wear resistance and preparation method thereof.
Background technology
Synthetic Leather has that gloss is soft, nature, and soft, kishke feel is strong, and flex endurant, the excellent feature such as anti-aging, be the ideal substitute of natural leather, be widely used in the industries such as clothes, shoemaking, case and bag, furniture; But Synthetic Leather is in the market too large with natural leather gap in water vapour permeability, wear resistance, the Synthetic Leather goods of water vapour permeability difference can make us feeling sultry, clammy, for these shortcomings, performance at present mainly through changing Synthetic Leather slurry is improved, but the technique changing Synthetic Leather slurry water vapour permeability and wear resistance is in the market more complicated, cost is higher, and effect is also not too obvious.

Have the synthetic leather slurry of high-wear resistance, the weight part of its constitutive material is: thermoplastic polyurethane 65, vulcabond 12, fatty alcohol-polyoxyethylene ether 3, aluminium silicon powder 7, aluminium sesquioxide 28, propylene oxide phenyl ether 1.0, triethylamine 3, sodium sulfate 0.5, MALEIC ANHYDRIDE 3.5, molybdenumdisulphide 5.5, polyvinylpyrrolidone 6, fallen flowers leave 9 and N-Methyl pyrrolidone 32.
There is the preparation method of the synthetic leather slurry of high-wear resistance, comprise the following steps:
(1) modification of fallen flowers leave: take fallen flowers leave by the weight part of constitutive material, fallen flowers leave is pulverized, dries, add little water and appropriate hydrogen peroxide, soak and with the sodium hydrogen carbonate solution of 0.1mol/L, pH value is adjusted to 7-8 after 30-40 minute, add 3-4% nano silicon and the 2-4% gelatin of Semen arachidis hypogaeae leaf quality again, stirring reaction 1-4 hour at 50-80 DEG C of temperature, in 105-110 DEG C of baking oven, 4-5 hour is dried again after suction filtration, washing, obtain modification fallen flowers leave, for subsequent use;
(2) all raw materials in formula are taken by weight, first molybdenumdisulphide is ground, then add in reactor, add deionized water to stir, N-Methyl pyrrolidone is added under whipped state, add the modification fallen flowers leave of step (1) after stirring, stir 2-3 hour at 6000-7000 rev/min;
(3) in the reactor of step (2), vulcabond, fatty alcohol-polyoxyethylene ether, aluminium silicon powder, propylene oxide phenyl ether, MALEIC ANHYDRIDE and polyvinylpyrrolidone is added successively, after stirring, be heated to 80-90 DEG C, other residue constitutive material is added again after insulation 1-2h, at the uniform velocity stir, obtain after stirring.
By obtained synthetic leather slurry with 150-180g/m
2blade coating amount be applied to separate-type paper surface, fit together with synthetic leather base cloth again after drying, upper paste, under 100-120 DEG C of condition, dry 5-6 minute, then under 80-100 DEG C of condition, solidify 18-20 hour.
Beneficial effect of the present invention:
High abrasion synthetic leather slurry of the present invention take aluminium sesquioxide as filler, more traditional slurry has better wear resistance, flame retardant resistance, higher humidity resistance, and when make moist and high temperature indeformable, not fragile, the fallen flowers leave of the molybdenumdisulphide simultaneously added and modification turn improves the wear resistance of slurry, thermotolerance while improving the strength of materials; Aluminium silicon powder add the mobility substantially improving slurry, preparation cost of the present invention is low, environmental protection.
